Latest Patents

One of her latest patents is the Gearbox Parking Brake. This invention features a gearing assembly that allows two or more interconnected gears to rotate in different directions or speeds. The design includes a first and second planetary gear assembly, along with a central gear that is concentrically positioned about a central rotation axis. The central gear is rotatably engaged with the planetary gear assemblies, and an input is connected to the central gear to operate these assemblies. Additionally, a gear engagement block is provided with sets of gear teeth that correspond to the planetary gear assemblies and the central gear. An actuator mechanism is connected to the gear engagement block, allowing it to shift between engaged and disengaged positions, thereby restricting movement of the gearing assembly when engaged.

Another significant patent is for a Vehicle with Hydrostatic Transmission. This invention includes a prime mover engine, a drive wheel, and a hydrostatic transmission. The prime mover engine has a vertical output shaft, while the hydrostatic transmission features a hydraulic pump with a vertical input shaft. A drive link connects the pump input shaft to the prime mover output shaft. The hydraulic motor also has a vertical output shaft, and an interface connector establishes fluid pressure communication between the hydraulic pump and motor. A gear set is positioned between the hydrostatic transmission and the drive wheel, incorporating a vertically disposed bevel gear connected to the motor output shaft and a horizontally disposed bevel gear linked to the drive wheel.
